BACKGROUND

Aspartic proteases, including renin, β-secretase (BACE), HIV protease, HTLV protease and plasmepsins I and II, are implicated in a number of disease states. In hypertension elevated levels of angiotensin I, the product of renin catalyzed cleavage of angioteninogen are present. Elevated levels of β amyloid, the product of BACE activity on amyloid precursor protein, are widely believed to be responsible for the amyloid plaques present In the brains of Alzheimer's disease patients. The viruses HIV and HTLV depend on their respective aspartic proteases for viral maturation. Plasmodium falciparum uses plasmepsins I and II to degrade hemoglobin.

In the renin-angiotensin-aldosterone system (RAAS) the biologically active peptide angiotensin II (Ang II) is generated by a two-step mechanism. The highly specific aspartic protease renin cleaves angiotensinogen to angiotensin I (Ang I), which is then further processed to Ang II by the less specific angiotensin-converting enzyme (ACE). Ang II is known to work on at least two receptor subtypes called AT₁ and AT₂. Whereas AT₁ seems to transmit most of the known functions of Ang II, the role of AT₂ is still unknown.

Modulation of the RAAS represents a major advance in the treatment of cardiovascular diseases (Zaman, M. A. et al Nature Reviews Drug Discovery 2002, 1, 621-636). ACE inhibitors and AT₁ blockers have been accepted as treatments of hypertension (Waeber B. et al., “The renin-angiotensin system: role in experimental and human hypertension”, in Berkenhager W. H., Reid J. L. (eds): Hypertension, Amsterdam, Elsevier Science Publishing Co, 1996, 489-519; Weber M. A., Am. J. Hypertens., 1992, 5, 247S). In addition, ACE inhibitors are used for renal protection (Rosenberg M. E. et al., Kidney International, 1994, 45, 403; Breyer J. A. et al., Kidney International, 1994, 45, S156), in the prevention of congestive heart failure (Vaughan D. E. et al., Cardiovasc. Res., 1994, 28, 159; Fouad-Tarazi F. et al., Am. J. Med., 1988, 84 (Suppl. 3A), 83) and myocardial infarction (Pfeffer M. A. et al., N Engl. J: Med, 1992, 327, 669).

Interest in the development of renin inhibitors stems from the specificity of renin (Kleinert H. D., Cardiovasc. Drugs, 1995, 9, 645). The only substrate known for renin is angiotensinogen, which can only be processed (under physiological conditions) by renin. In contrast, ACE can also cleave bradykinin besides Ang I and can be bypassed by chymase, a serine protease (Husain A., J. Hypertens., 1993, 11, 1155). In patients, inhibition of ACE thus leads to bradykinin accumulation causing cough (5-20%) and potentially life-threatening angioneurotic edema (0.1-0.2%) (Israili Z. H. et al., Annals of Internal Medicine, 1992, 117, 234). Chymase is not inhibited by ACE inhibitors. Therefore, the formation of Ang II is still possible in patients treated with ACE inhibitors. Blockade of the ATI receptor (e.g., by losartan) on the other hand overexposes other AT-receptor subtypes to Ang II, whose concentration is dramatically increased by the blockade of AT1 receptors. In summary, renin inhibitors are not only expected to be superior to ACE inhibitors and AT₁ blockers with regard to safety, but more importantly also with regard to their efficacy in blocking the RAAS.

Only limited clinical experience (Azizi M. et al., J. Hypertens., 1994, 12, 419; Neutel J. M. et al., Am. Heart, 1991, 122, 1094) has been generated with renin inhibitors because their peptidomimetic character imparts insufficient oral activity (Kleinert H. D., Cardiovasc. Drugs, 1995, 9, 645). The clinical development of several compounds has been stopped because of this problem together with the high cost of goods. It appears as though only one compound has entered clinical trials (Rahuel J. et al., Chem. Biol., 2000, 7, 493; Mealy N. E., Drugs of the Future, 2001, 26, 1139). Thus, metabolically stable, orally bioavailable and sufficiently soluble renin inhibitors that can be prepared on a large scale are not available. Recently, the first non-peptide renin inhibitors were described which show high in vitro activity (Oefner C. et al., Chem. Biol., 1999, 6, 127; Patent Application WO 97/09311; Maerki H. P. et al., Il Farmaco, 2001, 56, 21). The present invention relates to the unexpected identification of renin inhibitors of a non-peptidic nature and of low molecular weight. Orally active renin inhibitors which are active in indications beyond blood pressure regulation where the tissular renin-chymase system may be activated leading to pathophysiologically altered local functions such as renal, cardiac and vascular remodeling, atherosclerosis, and restenosis, are described.

“Oxo” refers to ═O. When an oxo group is a substituent on a carbon atom, they form a carbonyl group (—C(O)—). When one oxo group is a substituent on a sulfur atom, they form a sulfinyl (sulfoxide —S(O)—) group. When two oxo groups are a substituent on a sulfur atom, they form a sulfonyl (sulfone —S(O)₂—) group.

In certain instances herein when describing functional groups, “alkane”, “'cycloalkane” and the like are used interchangeably with “alkyl” and “cycloalkyl”, respectively. Thus, by way of example, “alkanesulfonyl” means an alkyl group attached to a sulfonyl moiety, and “cycloalkanesulfonyl” refers to a cycloalkyl group attached to a sulfonyl moiety.

Enantiomers, Diastereomers, and Salts

Certain compounds of Formula I may exist in various stereoisomeric or tautomeric forms. The invention encompasses all such forms, including active compounds in the form of essentially pure enantiomers, racemic mixtures, and tautomers.

The compounds of the invention may be present in the form of pharmaceutically acceptable salts. For use in medicines, the salts of the compounds of the invention refer to non-toxic “pharmaceutically acceptable salts.” Pharmaceutically acceptable salt forms include pharmaceutically acceptable acidic/anionic or basic/cationic salts.

Pharmaceutically acceptable acidic/anionic salts include, the acetate, benzenesulfonate, benzoate, bicarbonate, bitartrate, bromide, calcium edetate, camsylate, carbonate, chloride, citrate, dihydrochloride, edetate, edisylate, estolate, esylate, fumarate, glyceptate, gluconate, glutamate, glycollylarsanilate, hexylresorcinate, hydrobromide, hydrochloride, hydroxynaphthoate, iodide, isethionate, lactate, lactobionate, malate, maleate, mandelate, mesylate, methylsulfate, mucate, napsylate, nitrate, pamoate, pantothenate, phosphate/diphospate, polygalacturonate, salicylate, stearate, subacetate, succinate, sulfate, tannate, tartrate, teoclate, tosylate, and triethiodide salts.

It may be necessary and/or desirable during synthesis to protect sensitive or reactive groups on any of the molecules concerned. Representative conventional protecting groups are described in T. W. Greene and P. G. M. Wuts “Protective Groups in Organic Synthesis” John Wiley & Sons, Inc., New York 1999. Protecting groups may be added and removed using methods well known in the art.

The invention also includes various isomers and mixtures thereof. “Isomer” refers to compounds that have the same composition and molecular weight but differ in physical and/or chemical properties. The structural difference may be in constitution (geometric isomers) or in the ability to rotate the plane of polarized light (stereoisomers).

Stereoisomers are compounds which differ only in their spatial arrangement. Enantiomers are pairs of stereoisomers whose mirror images are not superimposable, most commonly because they contain an asymmetrically substituted carbon atom that acts as a chiral center. “Enantiomer” means one of a pair of molecules that are mirror images of each other and are not superimposable. Diastereomers are stereoisomers that are not related as mirror images, most commonly because they contain two or more asymmetrically substituted carbon atoms. The symbol “*” in a structural formula represents the presence of a chiral carbon center. “R” and “S” represent the configuration of substituents around one or more chiral carbon atoms. Thus, “R*” and “S*” denote the relative configurations of substituents around one or more chiral carbon atoms. When a chiral center is not defined as R or S, a mixture of both configurations is present.

“Racemate” or “racemic mixture” means a compound of equimolar quantities of two enantiomers, wherein such mixtures exhibit no optical activity; i.e., they do not rotate the plane of polarized light.

“Geometric isomer” means isomers that differ in the orientation of substituent atoms in relationship to a carbon-carbon double bond, to a cycloalkyl ring, or to a bridged bicyclic system. Atoms (other than H) on each side of a carbon-carbon double bond may be in an E (substituents are on opposite sides of the carbon-carbon double bond) or Z (substituents are oriented on the same side) configuration.

Atoms (other than H) attached to a carbocyclic ring may be in a cis or trans configuration. In the “cis” configuration, the substituents are on the same side in relationship to the plane of the ring; in the “trans” configuration, the substituents are on opposite sides in relationship to the plane of the ring. A mixture of “cis” and “trans” species is designated “cis/trans”.

“R,” “S,” “S*,” “R*,” “E,” “Z,” “cis,” and “trans,” indicate configurations relative to the core molecule.

The compounds of the invention may be prepared as individual isomers by either isomer-specific synthesis or resolved from an isomeric mixture. Conventional resolution techniques include forming the salt of a free base of each isomer of an isomeric pair using an optically active acid (followed by fractional crystallization and regeneration of the free base), forming the salt of the acid form of each isomer of an isomeric pair using an optically active amine (followed by fractional crystallization and regeneration of the free acid), forming an ester or amide of each of the isomers of an isomeric pair using an optically pure acid, amine or alcohol (followed by chromatographic separation and removal of the chiral auxiliary), or resolving an isomeric mixture of either a starting material or a final product using various well known chromatographic methods.

Biological Assay Procedures

The compounds of the invention have enzyme-inhibiting properties. In particular, they inhibit the action of the natural enzyme renin. The latter passes from the kidneys into the blood where it effects the cleavage of angiotensinogen, releasing the decapeptide angiotensin I which is then cleaved in the blood, lungs, the kidneys and other organs by angiotensin converting enzyme to form the octapeptide angiotensin II. The octapeptide increases blood pressure both directly by binding to its receptor, causing arterial vasoconstriction, and indirectly by liberating from the adrenal glands the sodium-ion-retaining hormone aldosterone, accompanied by an increase in extracellular fluid volume. That increase can be attributed to the action of angiotensin II. Inhibitors of the enzymatic activity of renin bring about a reduction in the formation of angiotensin I. As a result a smaller amount of angiotensin II is produced. The reduced concentration of that active peptide hormone is the direct cause of the hypotensive effect of renin inhibitors.

The action of renin inhibitors in vitro is demonstrated experimentally by means of a test which measures the increase in fluorescence of an internally quenched peptide substrate. The sequence of this peptide corresponds to the sequence of human angiotensinogen. The following test protocol is used. All reactions are carried out in a flat bottom white opaque microtiter plate. A 4 μL aliquot of 400 μM renin substrate (DABCYL-γ-Abu-Ile-His-Pro-Phe-His-Leu-Val-Ile-His-Thr-EDANS) in 192 μL assay buffer (50 mM BES, 150 mM NaCl, 0.25 mg/mL bovine serum albumin, pH7.0) is added to 4 μL of test compound in DMSO at various concentrations ranging from 10 μM to 1 nM final concentrations. Next, 100 μL of trypsin-activated recombinant human renin (final enzyme concentration of 0.2-2 nM) in assay buffer is added, and the solution is mixed by pipetting. The increase in fluorescence at 495 nm (excitation at 340 nm) is measured for 60-360 minutes at rt using a Perkin-Elmer Fusion microplate reader. The slope of a linear portion of the plot of fluorescence increase as a function of time is then determined, and the rate is used for calculating percent inhibition in relation to uninhibited control. The percent inhibition values are plotted as a function of inhibitor concentration, and the IC₅₀ is determined from a fit of this data to a four parameter equation. The IC₅₀ is defined as the concentration of a particular inhibitor that reduces the formation of product by 50% relative to a control sample containing no inhibitor. In the in vitro systems the compounds of the invention exhibit inhibiting activities at minimum concentrations of from approximately 5×10⁻⁵ M to approximately 10⁻¹² M. Preferred compounds of the invention exhibit inhibiting activities at minimum concentrations of from approximately 10⁻⁷ M to approximately 10⁻¹² M. (Wang G. T. et al. Anal. Biochem. 1993, 210, 351; Nakamura, N. et al. J. Biochem. (Tokyo) 1991, 109, 741; Murakami, K. et al. Anal Biochem. 1981, 110, 232).

The action of renin inhibitors in vitro in human plasma is demonstrated experimentally by the decrease in plasma renin activity (PRA) levels observed in the presence of the compounds. Incubations mixtures contained in the final volume of 250 μL 95.5 mM N,N-bis(2-hydroxyethyl)-2-aminoethanesulfonic acid, pH 7.0, 8 mM EDTA, 0.1 mM neomycin sulfate, 1 mg/mL sodium azide, 1 mM phenylmethanesulfonyl fluoride, 2% DMSO and 87.3% of pooled mixed-gender human plasma stabilized with EDTA. For plasma batches with low PRA (less than 1 ng/ml/hr) ˜2 pM of recombinant human renin was added to achieve PRA of 3-4 ng/ml/hr. The cleavage of endogenous angiotensinogen in plasma was carried out at 37° C. for 90 min and the product angiotensin I was measured by competitive radioimmunoassay using DiaSorin PRA kit. Uninhibited incubations containing 2% DMSO and fully inhibited controls with 2 μM of isovaleryl-Phe-Nle-Sta-Ala-Sta-OH were used for deriving percent of inhibition for each concentration of inhibitors and fitting dose-response data into a four parametric model from which IC₅₀ values, defined as concentrations of inhibitors at which 50% inhibition occurs, were determined.

The cardiac and systemic hemodynamic efficacy of selective renin inhibitors were evaluated in vivo in sodium-depleted, normotensive cynomolgus monkeys and in sodium-depleted, normotensive beagle dogs following a single oral and intravenous administration of the test compound. Arterial blood pressure was monitored by telemetry in freely moving, conscious animals.

Cynomolgus Monkey: Six male naïve cynomolgus monkeys weighing between 2.5 and 3.5 kg were used in the studies. At least 4 weeks before the experiment, the monkeys were anesthetized with ketamine hydrochloride (15 mg/kg, i.m.) and xylazine hydrochloride (0.7 mg/kg, i.m.), and were implanted into the abdominal cavity with a transmitter (Model #TL11M2-D70-PCT, Data Sciences, St. Paul, Minn.). The pressure catheter was inserted into the lower abdominal aorta via the femoral artery. The bipotential leads were placed in Lead II configuration. The animals were housed under constant temperature (19-25° C.), humidity (>40%) and lighting conditions (12 h light and dark cycle), were fed once daily, and were allowed free access to water. The animals were sodium depleted by placing them on a low sodium diet (0.026%, Expanded. Primate Diet 829552 MP-VENaCl (P), Special Diet Services, Ltd., UK) 7 days before the experiment and furosemide (3 mg/kg, intramuscularly i.m., Aventis Pharmaceuticals) was administered at −40 h and −16 h prior to administration of test compound.

For oral dosing, the renin inhibitors were formulated in 0.5% methylcellulose at dose levels of 10 and 30 mg/kg (5 mL/kg) by infant feeding tubes. For intravenous delivery, a silastic catheter was implanted into posterior vena cava via a femoral vein. The catheter was attached to the delivery pump via a tether system and a swivel joint. Test compound (dose levels of 0.1 to 10 mg/kg, formulated at 5% dextrose) was administered by continuous infusion (1.67 mL:/kg/h) or by bolus injection (3.33 mL/kg in 2 min).

Arterial blood pressures (systolic, diastolic and mean) and body temperature were recorded continuously at 500 Hz and 50 Hz, respectively, using the Dataquest™ A.R.T. (Advanced Research Technology) software. Heart rate was derived from the phasic blood pressure tracing. During the recording period, the monkeys were kept in a separate room without human presence to avoid pressure changes secondary to stress. All data were expressed as mean±SEM. Effects of the renin inhibitors on blood pressure were assessed by ANOVA, taking into account the factors dose and time compared with the vehicle group.

Beagle Dogs: Non-naive Beagle dogs (2 per sex) weighing between 9 and 11 kg were used in the studies. Each animal was implanted subcutaneously with a telemetry transmitter (Data Sciences) and the blood pressure catheter was inserted into the left femoral artery. The electrocardiogram leads were also tunneled subcutaneously to the appropriate anatomical regions. The animals were housed under constant temperature and lighting conditions, were fed once daily, and were allowed free access to water. A sodium depleted state was produced by placing them on a low-sodium diet (<4 meq/day, a combination of canned Prescription Diet canine h/d, from Hill's Pet Products and dry pellets from Bio-Serv Inc., Frenchtown, N.J.) beginning 10 days before the experiment, and furosemide (3 mg/kg i.m.; Aventis Pharmaceuticals) was administered at −40 and −16 h prior to administration of test compound.

A renin inhibitor was orally administered by orogastric gavage to all overnight fasted anaimals at a dose level of 30 mg/kg (4 mL/kg formulated in 0.5% methylcellulose). Food was given 4 h postdose. In some experiments, the renin inhibitor was administered by bolus i.v. at increasing dose levels of 1, 3 and 6 mg/kg (2, 6 and 20 mg/mL formulated in sterile saline). Cardiovascular parameters were collected continuously at least 80 min predose and 3 h postdose, followed by every 10 min for 5 h and every 30 min for 16 h postdose. The Dataquest™ ART (version 2.2) software package from DSI (Data Sciences International) was used to collect telemetered cardiovascular data.

The efficacy of the renin inhibitors was also evaluated in vivo in double transgenic rats engineered to express human renin and human angiotensinogen (Bohlender J, Fukamizu A, Lippoldt A, Nomura T, Dietz R, Menard J, Murakami K, Luft F C, Ganten D. High human renin hypertension in transgenic rats. Hypertension 1997, 29, 428-434).

Experiments were conducted in 6-week-old double transgenic rats (dTGRs). The model has been described in detail earlier. Briefly, the human renin construct used to generate transgenic animals made up the entire genomic human renin gene (10 exons and 9 introns), with 3.0 kB of the 5′-promoter region and 1.2 kB of 3′ additional sequences. The human angiotensinogen construct made up the entire human angiotensinogen gene (5 exons and 4 introns), with 1.3 kB of 5′-flanking and 2.4 kB of 3′-flanking sequences. The rats were purchased from RCC Ltd (Füllinsdorf, Switzerland). Radio telemetry transmitters were surgically implanted at 4 weeks of age. The telemetry system provided 24-h recordings of systolic, mean, diastolic arterial pressure (SAP, MAP, DAP, respectively) and heart rate (HR). Beginning on day 42, animals were transferred to telemetry cages. A 24 h telemetry reading was obtained. Rats were then dosed orally on the following 4 consecutive days (days 43-46). The rats were monitored continuously and allowed free access to standard 0.3%-sodium rat chow and drinking water.

The compounds of the invention are useful for ameliorating or treating disorders or diseases in which decreasing the levels of aspartic protease products is effective in treating the disease state or in treating infections in which the infectious agent depends upon the activity of an aspartic protease. In hypertension elevated levels of angiotensin I, the product of renin catalyzed cleavage of angioteninogen are present. Elevated levels of β amyloid, the product of BACE activity on amyloid precursor protein, are believed to be responsible for the amyloid plaques present in the brains of Alzheimer's disease patients. The viruses HIV and HTLV depend on their respective aspartic proteases for viral maturation. Plasmodium falciparum uses plasmepsins I and II to degrade hemoglobin.

The compositions of the invention include ocular, oral, nasal, transdermal, topical with or without occlusion, intravenous (both bolus and infusion), and injection (intraperitoneally, subcutaneously, intramuscularly, intratumorally, or parenterally). The composition may be in a dosage unit such as a tablet, pill, capsule, powder, granule, liposome, ion exchange resin, sterile ocular solution, or ocular delivery device (such as a contact lens and the like facilitating immediate release, timed release, or sustained release), parenteral solution or suspension, metered aerosol or liquid spray, drop, ampoule, auto-injector device, or suppository; for administration ocularly, orally, intranasally, sublingually, parenterally, or rectally, or by inhalation or insufflation.

The compositions of the invention may be administered in a form suitable for once-weekly or once-monthly administration. For example, an insoluble salt of the active compound may be adapted to provide a depot preparation for intramuscular injection (e.g., a decanoate salt) or to provide a solution for ophthalmic administration.

The dosage form containing the composition of the invention contains a therapeutically effective amount of the active ingredient necessary to provide a therapeutic effect. The composition may contain from about 5,000 mg to about 0.5 mg (preferably, from about 1,000 mg to about 0.5 mg) of a compound of the invention or salt form thereof and may be constituted into any form suitable for the selected mode of administration. The composition may be administered about 1 to about 5 times per day. Daily administration or post-periodic dosing may be employed.

For oral administration, the composition is preferably in the form of a tablet or capsule containing, e.g., 500 to 0.5 milligrams of the active compound. Dosages will vary depending on factors associated with the particular patient being treated (e.g., age, weight, diet, and time of administration), the severity of the condition being treated, the compound being employed, the mode of administration, and the strength of the preparation.

The oral composition is preferably formulated as a homogeneous composition, wherein the active ingredient is dispersed evenly throughout the mixture, which may be readily subdivided into dosage units containing equal amounts of a compound of the invention. Preferably, the compositions are prepared by mixing a compound of the invention (or pharmaceutically acceptable salt thereof) with one or more optionally present pharmaceutical carriers (such as a starch, sugar, diluent, granulating agent, lubricant, glidant, binding agent, and disintegrating agent), one or more optionally present inert pharmaceutical excipients (such as water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents, and syrup), one or more optionally present conventional tableting ingredients (such as corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearate, dicalcium phosphate, and any of a variety of gums), and an optional diluent (such as water).

Tablets may also be coated or otherwise compounded to provide a prolonged, control-release therapeutic effect. The dosage form may comprise an inner dosage and an outer dosage component, wherein the outer component is in the form of an envelope over the inner component. The two components may further be separated by a layer which resists disintegration in the stomach (such as an enteric layer) and permits the inner component to pass intact into the duodenum or a layer which delays or sustains release. A variety of enteric and non-enteric layer or coating materials (such as polymeric acids, shellacs, acetyl alcohol, and cellulose acetate or combinations thereof) may be used.

Compounds of the invention may also be administered via a slow release composition; wherein the composition includes a compound of the invention and a biodegradable slow release carrier (e.g., a polymeric carrier) or a pharmaceutically acceptable non-biodegradable slow release carrier (e.g., an ion exchange carrier).

Biodegradable and non-biodegradable slow release carriers are well known in the art. Biodegradable carriers are used to form particles or matrices which retain an active agent(s) and which slowly degrade/dissolve in a suitable environment (e.g., aqueous, acidic, basic and the like) to release the agent. Such particles degrade/dissolve in body fluids to release the active compound(s) therein.

EXAMPLE 6 3-((2-Bromophenyl)(3-methoxypropoxy)methyl)-1-(2-(trimethylsilyl)ethylsulfonyl)piperidine

Step 1. Ethyl 1-(2-(trimethylsilyl)ethylsulfonyl)piperidine-3-carboxylate

A 1 L flask equipped with a dropping funnel was charged with 2-(trimethylsilylethane)-sulfonyl chloride (7.5 g, 0.0374 mol, 1.0 equiv) and CH₂Cl₂ (150 mL). The flask was cooled to 0° C. and the dropping funnel was charged with a solution of racemic ethyl piperidine-3-carboxylate (7.34 g, 0.0467 mol, 1.25 equiv) and diisopropylethyl amine (12.1 g, 0.0935 mol, 2.5 equiv) in CH₂Cl₂ (50 mL). The solution of the amines was added and the resulting mixture was stirred for 3 h with concomitant warming to rt temperature. Analysis of the mixture by LC-MS showed a signal for the desired product. The reaction mixture was quenched by addition of 1.0 M HCl (100 mL). The layers were separated and the organic layer washed with additional aqueous HCl, then brine. It was dried over Na₂SO₄, filtered and evaporated to yield ethyl 1-(2-(trimethylsilyl)ethanesulfonyl)piperidine-3-carboxylate (10.63 g, 88%) as an amber syrup which was of sufficient purity to use in the next step. ¹H NMR (CDCl₃) δ −0.01 (s, 9H), 0.96 (m, 2H), 1.23 (t, 3H), 1.4-1.6 (m, 4H), 1.78 (M, 1H), 2.03 (m, 1H), 2.53 (m, 1H), 2.79 (m, 2H), 2.95 (d of d, 1H), 3.61 (m, 1H), 3.82 (m, 1H), 4.08, (q, 2H).

Step 2. (1-(2-(Trimethylsilyl)ethylsulfonyl)piperidin-3-yl)methanol

Ethyl 1-(2-(trimethylsilyl)ethanesulfonyl)piperidine-3-carboxylate (9.00 g, 28 mol) was dissolved in THF (200 mL) in a three-neck 500 mL flask and cooled to 0° C. A solution of LiBH₄ (2.0 M in THF, 28 mL, 0.056 mol, 2.0 equiv) was added via addition funnel. The mixture was allowed to warm to rt and stir for 15 h. Significant amounts of the starting ester remained; an additional charge of the LiBH₄ solution (28 mL, 0.056 mol) was added and the mixture stirred for an additional 17 h. After this period analysis by LC-MS showed consumption of the starting ester. The mixture was cooled to 0° C. and the excess LiBH₄ was quenched by dropwise addition of MeOH (100 mL). The volatile materials were removed and the residue partitioned between ether (100 mL) and 1.0 M aq HCl (100 mL). The layers were separated and the aqueous layer extracted with additional ether (3×50 mL). The combined organic extracts were washed with brine and dried over Na₂SO₄. The clear solution was evaporated to yield (1-(2-(trimethylsilyl)ethylsulfonyl)piperidin-3-yl)methanol (5.25 g, 67%) as a white solid which was of sufficient purity to use in the next step. ¹H NMR (CDCl₃) δ 0.00 (s, 9H), 0.95 (m, 2H), 1.21 (m, 1H), 1.5-8 (m, 5H), 2.75-2.82 (m, 3H), 2.91 (t of d, 1H), 3.53 (m, 2H), 3.62 (d of d, 1H).

Step 3. 1-(2-(Trimethylsilyl)ethylsulfonyl)piperidine-3-carbaldehyde

A three neck 500-mL flask equipped with a dropping funnel was charged with of anhydrous CH₂Cl₂ (100 mL) and oxalyl chloride (2.64 g, 20.7 mmol, 1.1 equiv). The solution was cooled to −78° C. under nitrogen. A solution of DMSO (2.93 g, 37.6 mmol, 2.0 equiv) in CH₂Cl₂ (10 mL) was added dropwise to the oxalyl chloride over a 15 minute period, and the resulting solution stirred for 30 min at −78° C. A solution of 1-(2-(trimethylsilyl)ethanesulfonyl)-3-hydroxymethylpiperidine (5.25 g, 18.8 mmol, 1.0 equiv) in CH₂Cl₂ (30 mL) was added dropwise over a 30 min period, and the resulting mixture stirred for 30 min at −78° C. Triethylamine (9.51 g, 94.4 mmol, 5.0 equiv) was added dropwise to the mixture over a 30 min period. The resulting white slurry was allowed to warm to 0° C. and stir for 30 min. Analysis of the mixture by LC-MS showed consumption of the alcohol. Water (200 mL) was added and the layers were separated. The organic layer was washed with brine and dried over Na₂SO₄. The aldehyde was purified by flash chromatography on 120 g of silica, eluting with 0 to 50% EtOAc in hexanes. Fractions containing the desired aldehyde were visualized by staining with 2,4-dinitrophenylhydrazine on silica gel. Removal of the solvent afforded 1-(2-trimethylsilyl(ethanesulfonyl))piperidine-3-carbaldehyde (3.8 1 g, 73%) as a white solid. ¹H NMR (CDCl₃) δ −0.15 (s, 9H), 0.96 (m, 2H), 1.5-1.77 (m, 4H), 1.95 (M, 1H), 2.54 (m, 1H), 2.82 (m, 2H), 2.95 (m, 1H), 3.17 (d of d, 1H), 3.44 (m, 1H), 3.72 (m, 1H), 9.64 (s, 1H).

Step 4. (2-Bromophenyl)(1-(2-(trimethylsilyl)ethylsulfonyl)piperidin-3-yl)methanol

A three neck 200-mL flask was charged with anhydrous THF (150 mL) and 1-bromo-2-iodobenzene (5.81 g, 20.5 mmol, 1.5 equiv), and cooled to −40° C. Isopropyl magnesium bromide (1.0 M in THF, 19.9 mL, 19.9 mmol, 1.45 equiv) was added to the solution via syringe at a rate such that the internal temperature did not rise above −35° C. An aliquot was removed, quenched with water and analyzed by LC-MS. The observed amount of bromobenzene showed >90% conversion to the desired Grignard reagent. A solution of 1-(2-trimethylsilyl-(ethanesulfonyl))piperidine-3-carbaldehyde (3.8 g, 13.7 mmol) in 20 mL of THF was added to solution containing the Grignard reagent at such a rate that the internal temperature did not rise above −35° C. The mixture was stirred for 1 h at −40° C.; after this period LC-MS analysis of an aliquot showed consumption of the aldehyde and formation of two peaks with the desired mass, consistent with formation of two diastereomers. The mixture was quenched with methanol and the THF removed in vacuo. The resulting solid was partitioned between EtOAc and water, and filtered through a pad of Celite to remove a sticky white solid. The layers were separated and the aqueous layer was extracted with additional EtOAc. The combined organic extracts were washed with brine, dried over Na₂SO₄, filtered, and evaporated. The mixture of alcohols was purified by flash chromatography on 120 g silica, eluting with 0 to 50% EtOAc in hexanes. No attempt was made to separate the two diastereomers. This afforded (2-bromophenyl)(1-(2-(trimethylsilyl)ethanesulfonyl)piperidin-3-yl)methanol (3.64 g, 61%) as a white foam. ¹H NMR (CDCl₃) δ 0.01 (s, 9H), 0.95-2.06 (m, 8H), 2.6-3.0 (m, 6H), 3.6-3.9 (m, 3H), 4.96 (bs, 1H), 7.13 (m, 1H), 7.29 (m, 1H), 7.44 (m, 2H).

Step 5. 3-((2-Bromophenyl)(3-methoxypropoxy)methyl)-1-(2-(trimethylsilyl)ethylsulfonyl)piperidine

A 250-mL three neck flask fitted with a reflux condenser was charged with NaH (60% in mineral oil, 644 mg of material, 16.1 mmol, 5.0 equiv). Anhydrous THF (80 mL) was added. A solution of (2-bromophenyl)(1-(2-(trimethylsilyl)ethanesulfonyl)piperidin-3-yl)methanol (1.4 g, 3.22 mmol, 1.0 equiv) in 10 mL of THF was slowly added via syringe. After cessation of hydrogen evolution, a solution of 3-methoxypropyl methanesulfonate (2.2 g, 12.8 mmol, 4.0 equiv) in 10 mL of THF was added and the resulting mixture was heated to reflux. After 1.0 h the signals for the starting material in the LC-MS were consumed and a new peak with M+Na for the desired product was observed. The mixture was allowed to cool to rt and excess NaH was quenched with water. The layers were separated and the aqueous layer was extracted with EtOAc. The combined organic fractions were washed with brine and purified by flash chromatography on silica gel (40 g) eluting with 0-25% EtOAc in hexanes. This afforded 3-((2-bromophenyl)(3-methoxypropoxy)methyl)-1-(2-(trimethylsilyl)ethylsulfonyl)piperidine (1.2 g, 73%) as a clear syrup containing a mixture of two diastereomers. No attempt was made to separate the diastereomers. MS ESI +ve m/z 506 (M+1).

The tube was sealed and the resulting purple solution was degassed by three evacuate/N₂ backfill cycles, then placed in a microwave reactor and heated to 120° C. for 20 min. The resulting brown solution was analyzed by LC-MS, which showed consumption of the starting bromide and formation of a new peak with desired mass. Solid KF.H₂O (500 mg) was added, and the mixture stirred for 30 min in the air. The residue was partitioned between EtOAc and water. The layers were separated and the aqueous layer extracted with additional EtOAc. The combined organic extracts were washed with brine, dried over Na₂SO₄ and evaporated.

Step 1. Diisopropyl-3,3-Dimethoxycyclobutane-1,1-Dicarboxylate

Following the procedure of Pigou and Scheisser (J. Org. Chem. 1988, 53, 3841), a 500 mL, 3-neck flask, fitted with a reflux condenser and thermocouple, was charged with NaH (60% in mineral oil, 4 g, 0.210 mol). DMF (100 mL) was added via syringe and the slurry was stirred under N₂. Diisopropyl malonate was added at a rate so that the internal temperature did not rise above 70° C. After the H₂ evolution had ceased, the flask was briefly opened and 1,3-dibromo-2,2-dimethoxypropane was added. The bath temperature was raised to 145° C. The reaction mixture was maintained at this temperature for 48 h. After this time the dark brown mixture was allowed to cool to rt. Water (50 mL) was added and the solvents were removed in vacuo. The residue was partitioned between ether (200 mL) and sat'd aq NH₄Cl (200 mL) and the mixture filtered through a pad of Celite to remove solid impurities. The aqueous layer was extracted with ether (2×100 mL). The combined ether extracts were washed with brine, dried over Na₂SO₄, filtered and evaporated. Flash chromatography (SiO₂, 0-25% EtOAc in hexanes) gave semi-pure diisopropyl-3,3-dimethoxycyclobutane-1,1-dicarboxylate (28.5 g), which was used in the next step.

Step 2. 3-Oxocylobutanecarboxylic Acid

Diisopropyl-3,3-dimethoxycyclobutane-1,1-dicarboxylate (28.5 g) was added to 75 mL of 20% aq HCl. The mixture was heated to reflux for 60 h. The brown solution was cooled to rt and satd with NaCl. The aqueous layer was extracted with ether (7×75 mL) and stripped to yield 3-oxocylobutanecarboxylic acid (12.2 g) as a brown oil.

Step 3. Butyl 3-oxocylobutanecarboxylate

3-Oxocylobutanecarboxylic acid (12.2 g, <0.107 mol, 1.0 equiv) and DMAP (10.5 g, 0.856 mol) were dissolved in butanol (100 mL) and the mixture cooled to 0° C. DCC (24.2 g, 0.118 mol, 1.2 equiv) was added as a solid. The mixture was allowed to stir for 15 h with concomitant warming to rt. The mixture was filtered through a pad of Celite. The filter cake was washed with hexanes. The filtrate was washed with 1.0 M aq HCl, sat'd aq NaHCO₃ and brine. Evaporation of the solvent afforded a brown oil. This was purified by flash chromatography (SiO₂, 0-20% EtOAc). The fractions which stained with 2,4-dinitrophenylhydrazine on tlc were pooled and evaporated to yield a pale yellow oil which was dissolved in hexane and filtered through Celite. The filtrate was evaporated to yield butyl 3-oxocylobutanecarboxylate (4.97 g) as a clear oil.

Step 4. Butyl 3,3-difluorocylobutanecarboxylate

The ester (4.97 g, 0.0292 mol, 1.0 equiv) was dissolved in CH₂Cl₂ and cooled to 0° C. DAST (11.5 mL, 0.0876 mol, 3.0 equiv) was added via syringe and the mixture was stirred overnight with warming to rt. TLC analysis showed no spots which stain with 2,4-dinitrophenylhydrazine. The mixture was cooled to 0° C. and sat'd NaHCO₃ was added, followed by 1.0 M aq NaOH till the pH>14. The layers were separated and the aqueous layer was extracted with CH₂Cl₂. The combined organic layers were dried over Na₂SO₄ and evaporated to leave butyl 3,3-difluorocylobutanecarboxylate (5.5 g) as a brown oil, which was used in the next step.

Step 5. (3,3-Difluorocylobutyl)methanol

A three-neck, 500 mL flask was charged with LiAlH₄ (2.4 g, 63 mmol, 2.2 equiv) and ether (140 mL) and cooled to −40° C. A solution of butyl 3,3-difluorocylobutanecarboxylate (5.5 g, 28.6 mmol, 1.0 equiv) in ether (20 mL) was added dropwise over a 20 min. The excess LiAlH₄ was quenched by sequential addition of water (2.5 mL), 10% aq NaOH (2.5 mL) and celite (10 g). The mixture was stirred for 30 min and diluted with EtOAc (100 mL). The mixture was filtered through a pad of celite. The filtrate was washed with brine, dried over Na₂SO₄, filtered and evaporated. This afforded (3,3-difluorocylobutyl)methanol (2.4 g) contaminated with ca 10% butanol. This crude material was used in the subsequent step.

Step 6. (3,3-difluorocyclobutyl)methyl 4-bromobenzenesulfonate

A round bottom flask was charged with (3,3-difluorocylobutyl)methanol (1.0 g, 8.2 mmol, 1.0 equiv), 4-bromobenzenesulphonyl chloride (2.2 g, 8.6 mmol, 1.05 equiv) and CH₂Cl₂ (50 mL). The mixture was cooled to 0° C. and triethylamine (2.07 g, 2.89 mL, 20.5 mmol, 2.5 equiv) was added via syringe. The mixture stirred for 12 h with warming to rt. After this time 1.0 M aq HCl (50 mL) was added. The layers were separated, the organic layer was extracted with CH₂Cl₂ (50 mL) and the combined organic layers were washed with brine, dried over Na₂SO₄, filtered and evaporated. The compound was purified by flash chromatography on silica, eluting with 0-30% EtOAc in hexanes. This afforded (3,3-difluorocyclobutyl)methyl 4-bromobenzenesulfonate (2.7 g, 95%) as an off white solid.

In a separate 3-neck, 100 mL flask NaH (60 wt % in oil, 352 mg, 8.82 mmol, 6 equiv) was slurried in dry DMF (20 mL). The flask was cooled to 0° C. and diethyl-2-acetamidomalonate was added via syringe. After gas evolution ceased, the solution of the (3,3-difluorocyclobutyl)methyl 4-bromobenzenesulfonate and NaI In DMF was added. The resulting solution was heated to 45° C. for 17 h. After this time no remaining brosylate or iodide was observed by TLC and LC-MS. The mixture was quenched by dropwise addition of water (10 mL) and the DMF was removed in vacuo. The residue was partitioned between ether and water and the layers separated. The aqueous layer was extracted with additional ether and the combined organic layers were washed with brine. The residue was evaporated and the desired product was purified by flash chromatography on silica, eluting with 0 to 50% EtOAc in hexanes. The fractions were stained with ceric ammonium molybdate; the desired product is contained in the second spot. This afforded diethyl 2-acetamido-2-((3,3-difluorocyclobutyl)methyl)malonate (474 mg, 99%).

Diethyl 2-acetamido-2-((3,3-difluorocyclobutyl)methyl)malonate (474 mg, 1.47 mmol) was slurried in 18% HCl (30 mL) and the mixture was heated to reflux for 8 h. After this time LC-MS showed complete conversion to the desired product. The solvent was removed to leave the hydrochloride of 2-amino-3-(3,3-difluorocyclobutyl)propanoic acid as an off-white solid which was used directly in the next step. A quantitative yield was assumed.

Step 9. 2-(2-(Trimethylsilyl)ethoxycarbonyl)amino-3-(3,3-difluorocyclobutyl)propanoic acid

The crude HCl salt 2-amino-3-(3,3-difluorocyclobutyl)propanoic acid (0.74 mmol) was dissolved in dioxane (5 mL) and 1.0 M aq NaOH 2.5 mL). Teoc-OSu (213 mg, 0.820 mmol, 1.1 equiv) was added and the mixture was stirred overnight at rt. The solvent was removed and the residue was taken up in water (˜5 mL). Citric acid (10% weight solution) was added till pH<4 and the mixture was extracted with EtOAc. The organic extract was dried over Na₂SO₄, filtered and solvent was removed to yield 2-(2-(trimethylsilyl)ethoxycarbonyl)amino-3-(3,3-difluorocyclobutyl)propanoic acid (273 mg) as a white foam. ¹H and ¹⁹F NMR were consistent with the desired product contaminated with Teoc-OSu.

Step 10. 2-(Trimethylsilyl)ethyl 3-(3,3-difluorocyclobutyl)-1-hydroxypropan-2-ylcarbamate

Crude 2-(2-(trimethylsilyl)ethoxycarbonyl)amino-3-(3,3-difluorocyclobutyl)propanoic acid (273 mg, 0.844 mmol) was dissolved in THF (5 mL) and the solution was cooled to −10° C. N-methylmorpholine (95 mg, 0.929 mmol, 1.1 equiv) was added and the mixture stirred for 15 min. After this time isobutyl chloroformate (127 mg, 0.929 mmol, 1.1 equiv) was added. After stirring for 30 min LC-MS showed remaining starting material. The procedure was repeated with an additional 0.55 equiv of the amine and chloroformate. This consumed all of the starting material. The reaction mixture was quickly filtered through a pad of celite into a solution of NaBH₄ (128 mmol, 3.4 mmol, 4.0 equiv) in water (4 mL). The filter cake was washed with an additional dry THF (5 mL). LC-MS analysis showed formation of the desired alcohol. The solvent was removed and the residue partitioned between EtOAc and brine. The layers were separated and the aqueous layer extracted with additional EtOAc. The combined organic layers were dried over Na₂SO₄. The solvent was removed to yield 2-(trimethylsilyl)ethyl 3-(3,3-difluorocyclobutyl)-1-hydroxypropan-2-ylcarbamate (240 mg, 90%) as an orange oil. ¹H and ¹⁹F NMR were consistent with the desired product.

Step 11. 2-(2-(Trimethylsilyl)ethoxycarbonylamino)-1-(3,3-difluorocyclobutyl)-3-(N-(t-butoxycarbonyl)-N-methylamino)-propane

2-(Trimethylsilyl)ethyl 3-(3,3-difluorocyclobutyl)-1-hydroxypropan-2-ylcarbamate (240 mg, 0.776 mmol) was dissolved in CH₂Cl₂ (4 mL) and the solution was cooled to 0° C. DIEA (301 mg, 2.32 mmol, 3.0 equiv) was added followed by MsCl (133 mg, 1.16 mmol, 1.5 equiv) and the mixture was stirred for 30 min at 0° C. LC-MS analysis showed consumption of the alcohol and formation of the desired mesylate. The reaction was quenched by addition of aq citric acid (10% by weight). The layers were separated and the aqueous phase was extracted with additional CH₂Cl₂. The combined organic layers were dried over Na₂SO₄, filtered and solvent was removed. The residue was taken up in methylamine solution (30 wt % in ethanol, 10 mL). Methanol was added dropwise to aid dissolution. The mixture was divided into three 4 mL portions. Each portion was separately heated to 150° C. for 7 min in a CEM microwave reactor. The four reaction mixtures were combined and volatile materials were removed. The residue was dissolved in acetonitrile (7 mL) and 1.0 M aq NaOH (2.0 mL) was added, followed by Boc₂O (186 mg, 0.854 mmol, 1.1 equiv). After 1 h starting amine was still observed by LC-MS and additional Boc₂O (1.1 equiv) was added. After 1 h all the amine was converted into the Boc derivative. The solvent was removed in vacuo and the residue was taken up in EtOAc and water. The layers were separated and the organic layer was washed with sat'd aq NaHCO₃, brine and evaporated. The diamine was purified by flash chromatography on 12 g of silica, eluting with a 0 to 50% EtOAc in hexanes gradient.

The mixture was stirred at −78° C. for 2 h, then tightly stoppered and the dry ice/IPA bath placed in a −15 C freezer for 19 h. After this time LC-MS analysis showed consumption of the iodide and formation of the desired product (M+H⁺). The reaction was quenched by addition of satd aq NH₄Cl (10 mL) and the THF removed in vacuo. The residue was partitioned between EtOAc and H₂O. The water layer was extracted with additional EtOAc and the combined organic layers washed with brine, dried over dried over Na₂SO₄, filtered and evaporated. The desired (2S,5R)-2-(((1r,3R,4S)-3,4-difluorocyclopentyl)methyl)-5-isopropyl-3,6-dimethoxy-2,5-dihydropyrazine, contaminated with the starting and (R)-2-isopropyl-3,6-dimethoxy-2,5-dihydropyrazine, was used directly in the next step.

The pyrazine mixture was dissolved in 1:1 acetonitrile/1.0 M aqueous HCl (200 mL). The mixture was stirred for 7 h at rt. The volatile components were removed in vacuo. The residue was dissolved in 1:1 acetonitrile/water (100 mL). To this solution was added K₂CO₃ (15.2 g, 0.110 mol, 5.0 equiv) and CbzOSu (10.9 g, 43.6 mmol, 3.0 equiv) and the resulting mixture allowed to stir for 17 h. After this time the volatile materials were removed and the residue was partitioned between EtOAc and water. The layers were separated and the organic layer was washed with satd aq NaHCO₃ and brine, dried over Na₂SO₄ filtered, and evaporated. The crude amino acid derivative was purified by flash chromatography, on silica, eluting with 0 to 47% EtOAc in hexanes. This afforded (S)-methyl 2-(benzyloxycarbonylamino)-3-((1R,3R,4R)-3-fluoro-4-hydroxycyclopentyl)propanoate (4.4 g, 89% yield).

Step 3. (S)-methyl 2-(benzyloxycarbonylamino)-3-((1r,3R,4S)-3,4-difluorocyclopentyl)propanoate

(S)-methyl 2-(benzyloxycarbonylamino)-3-((1R,3R,4R)-3-fluoro-4-hydroxycyclopentyl)propanoate (4.4 g, 12.9 mmol, 1.0 equiv) was dissolved in THF (50 mL) and cooled to 0° C. To this solution was added C₄F₉SO₂F (7.86 g, 25.93 mmol, 2.0 equiv), NEt₃(HF)₃ (4.18 g, 25.93 mmol, 2.0 equiv), and NEt₃ (7.84 g, 77.8 mmol, 6.0 equiv). The resulting mixture was allowed to stir for 72 h. After this time the solution was filtered through a pad of silica. The silica was washed with additional THF and the filtrate was transferred to a separatory funnel. The solution was washed with saturated NaHCO₃ and brine and evaporated. The desired vicinal difluoride was purified by flash chromatography on silica. This afforded (S)-methyl 2-(benzyloxycarbonylamino)-3-((1r,3R,4S)-3,4-difluorocyclopentyl)propanoate (3.0 g). Unreacted starting alcohol (818 mg) was also recovered.

Step 4. 2-(trimethylsilyl)ethyl (R)-2-amino-3-((1r,3R,4S)-3,4-difluorocyclopentyl)propyl(methyl)carbamate

LiAlH₄ (1.0 g, 26.5 mmol, 3.0 equiv) was slurried in THF (100 mL) and cooled to −78° C. A solution of (S)-methyl 2-(benzyloxycarbonylamino)-3-((1r,3R,4S)-3,4-difluorocyclopentyl)propanoate (3.0 g, 8.84 mmol) in THF (20 mL) was added over 20 min. After this time LC-MS analysis showed no remaining starting material. The mixture was warmed to 0° C. and brine (7 mL) was added dropwise, followed by ca 10 g of Celite. The thick slurry was stirred for 0.5 h, and filtered through a pad of Celite. The clear solution was evaporated to yield benzyl (S)-1-((1r,3R,4S)-3,4-difluorocyclopentyl)-3-hydroxypropan-2-ylcarbamate as a thick syrup (1.8 g, 65% yield).

A 250-mL flask was charged with the above alcohol (1.8 g, 5.75 mmol), brosyl chloride (2.94 g, 11.5 mmol, 2.0 equiv), DMAP (351 mg, 2.87 mmol, 0.5 equiv) and 5:1 CH₂Cl₂:pyridine (120 mL). The mixture was allowed to stir for 17 h at rt. After this time the volatile materials were removed in vacuo and the residue was partitioned between EtOAc and 1.0 M aq HCl. The layers were separated, and the organic layer evaporated. (S)-2-(benzyloxycarbonylamino)-3-((1r,3R,4S)-3,4-difluorocyclopentyl)propyl 4-bromobenzenesulfonate was purified by flash chromatography on silica gel, eluting with 0-80% EtOAc in hexanes.

The above brosylate was dissolved in 30% NH₂Me in EtOH (100 mL). The mixture was heated at reflux for 15 h. After this time the solvent was removed and the residue was dissolved in fresh 30% NH₂Me in EtOH (100 mL), and the mixture was heated to reflux for an additional 8 h. After this time the volatile materials were removed and the residue was dissolved in 1:1 CH₃CN:10% aqueous K₂CO₃ (40 mL). TeocOSu (2.22 g, 8.83 mmol, 1.5 equiv) was added and mixture stirred for 4 h. LC-MS showed consumption of the free amine. The acetonitrile was removed in vacuo and the product was extracted with EtOAc (2×20 mL). The combined organic extracts were dried over Na₂SO₄, filtered, and evaporated. 2-(trimethylsilyl)ethyl (S)-2-(benzyloxycarbonylamino)-3-((1r,3R,4S)-3,4-difluorocyclopentyl)propyl(methyl)carbamate was isolated by flash chromatography on silica gel eluting with 0-7% MeOH in CH₂Cl₂.

A crude sample of the above diamine dissolved in MeOH (10 mL) was added to a 250-mL Parr pressure bottle containing 10% Pd (ca 100 mg) on carbon and MeOH (7 mL). The bottle was placed in a hydrogenation shaker and pressurized to 45 psi of H₂, then evaporated. This procedure was repeated twice, the mixture was placed in the shaker for 3 h. After this time the Cbz group was cleanly removed. The catalyst was removed by filtration through Celite and the volatile materials removed to afford 2-(trimethylsilyl)ethyl (R)-2-amino-3-((1r,3R,4S)-3,4-difluorocyclopentyl)propyl(methyl)carbamate (109 mg) as a clear oil. This amine was of sufficient purity to employ in subsequent steps.
